WI: Britain backs Japan in 1905

What if Britain decides to back Japan over the peace negotiations at the end of the Russo-Japanese War? Ultimately, Britain's alliance with Japan was meant to check Russian ambitions in the Far East, and Britain acts on the grounds that giving Japan Karafuto and Kuril would decisively check just those ambitions once and for all. Ultimately Japan gains Karafuto and Kuril, along with heavy indemnity, while Britain loans heavily to Russia (effectively binding them closer to Britain due to their increased dependence on British capital to stay afloat) in the aftermath.

What butterflies would this change in history release into the TLs?
